the Supermoon

A supermoon is the coincidence of a full moon or a new moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from Earth The technical name is the perigee-syzygy of the Earth-Moon-Sun system. The term "supermoon" is not astronomical, but originated in modern astrology.The association of the Moon with both oceanic and crustal tides has led to claims that the supermoon phenomenon may be associated with increased risk of events such as earthquakes and volcanic eruptions, but the evidence of such a link is widely held to be unconvincing.

The most recent occurrence was on August 29, 2015.

The opposite phenomenon, an apogee-syzygy, has been called a micromoon, though this term is not as widespread as supermoon.

The name SuperMoon was coined by astrologer Richard Nolle in 1979, arbitrarily defined as: ...a new or full moon which occurs with the Moon at or near (within 90% of) its closest approach to Earth in a given orbitIn short, Earth, Moon and Sun are all in a line, with Moon in its nearest approach to Earth.    Perigee is the point at which the Moon is closest in its orbit to the Earth,
